Anti-RBM42 antibodies are used in the immunodetection of the protein RNA binding motif protein 42. In humans, the canonical protein has a reported length of 480 amino acid residues and a mass of 50.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the RRM RBM42 protein family, Rbm42 is known to bind (via the RRM domain) to the 3'-untranslated region (UTR) of CDKN1A mRNA. Synonyms for this target antigen include RNA-binding protein 42. RBM42 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Western Blot is the most common application for the Rbm42 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
